BOAT CLAMP-SCREW.

Specification of Letters Patent.

Patented July 20, 1915.

Application filed December 15, 1913. SerialNo. 806,855.

To all whom it may concern:

Be it known that I, CHARLES BENNETT, a citizen of the United States of America, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Boat Clamp-Screws, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a clamp intended to be used in boat building and the principal object of the invention is to so construct the clamp that it may be securely held" in place while the flooring board is being.

moved. tightly into engagement with the board already secured.

With the above and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed. 1 i

In the accompanying drawing :Figure 1 is a perspective view of the clamp. Fig. 2 is a view showing the bottom of a boat in section and the clamp in elevation. Fig. 3 is a top plan view showing the clamp in position. Fig. 4 is a section along the line l4:, in Fig. 2. Fig. 5 is a section along the line 5-5, in Fig. 4. Fig. 6 is a section along the line 66, in Fig. 2.

This clamp comprises a standard 10 having an enlarged base 11 and having its up per end portion bent to form an arm 12 extending from the standard and terminating in a threaded sleeve 13. A threaded shaft 14 passes through the sleeve 13 and is provided at its upper end with a head 15 through which a bar 16 passes, and at its lower end with a head 17 which is rotatably connected with the threaded shaft by means of the ball connection 18 shown in Fig. 6. An arm 19 extends from the base 11 at substantially right angles to the base and parallel to the arm 12, and is provided with a threaded opening through which a threaded shaft 20 passes. This shaft 20 is provided with a head 21 through which a bar 22 passes and has its inner end provided with a head 23 rotatably connected with the shaft in -a' manner similar to that provided for the head 17 This clamp is put in place with the arm 5 extending beneath the rib 24 and the shaft 14 is then turned to tighten the clamp and rigidly connect the clamp with the rib. As soon as the clamp is tightly connected with the rib the shaft 20 is then turned so that its head engages the block 25 and presses the plank 26 tightly against the plank 27 which has been already secured. As soon as the plank 26 has been secured the shaft 20 can be loosened and the shaft 1A then loosened a suflicient amount to permit the clamp to be moved along the rib a sufficient distance to permit a new board to be put in place.

By the construction of this clamp, the clamp is prevented from turning when the board 26 is being tightened, and the clamp is thus prevented from slipping from the rib.

Having thus describedthe invention what is claimed as new, is

A clamp of the class described comprising a standard having a laterally extending arm formed upon one end thereof, said standard provided with an enlarged base portion, a laterally extending arm formed integral upon said base portion, said last-mentioned arm extending parallel to said first-mentioned arm, a threaded shaft passing through the outer end of said first-mentioned arm so as to extend toward said last-mentioned arm, a threaded shaft passing through said last-mentioned arm and extending at right arms and standard forming a U-shaped clamp body, said first-mentioned shaft and said last-mentioned arm being adapted to support the clamp in engagement with a support, the shaft passing through said lastmentioned arm being adapted to engage a movable object for holding the same in its correct position.

In testimony whereof I hereunto afiix my signature in presence of two witnesses.

CHARLES BENNETT.
